     [ https://issues.apache.org/jira/browse/HADOOP-5485?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Vinod K V updated HADOOP-5485:
------------------------------

    Attachment: HADOOP-5485.txt

Attaching patch to use webinterface.private.actions for disabling changes to priority/pool from the scheduler servlet. The patch also disables changes to the scheduling mode from the UI.  The only nit is that this makes it impossible to change scheduling mode even by admins if webinterface.private.actions is disabled.

> FS scheduler should have some mechanism to authorize people who can access the advanced scheduler url http://jobtracker.com:port/scheduler .  In large clusters , which has hundreds of users, any user can access the url now and change the priority of his/her runing job. We don't want the users to change the job priority. So we should restrcit users accessing the link and only admins should have access to the link.
